Description
ferenzspannungsquelle 5, einem Regler 6, einem Mittelwertbildner 7 und einem Umkehrverstärker 8 bestehtreference voltage source 5, a regulator 6, an averaging device 7 and an inverting amplifier 8
Gemäß Fig.4 wird der von der Rsferehzspanhung Us ausgehende zeitlineare Spannungsanstieg am Ausgang des Integrators des Sägezahngenerators 2 durch s einen immer im Nulldurchgang eier Wechselspannung erzeugten Synchronisierimpuls abgebrochen und infolge Kondensatorschnellentladung auf Null geführt Die sich hierdurch ergebende Sägezahnspannung Lh wird auf den Mittelwertbildner 7 geschaltet und dessen Ausgangsspannung mit dem Faktor 2 verstärktAccording to Figure 4, the outgoing of the Rsferehzspanhung Us time-linear increase in voltage at the output of the integrator of the sawtooth generator 2 by s an ever broken eggs AC synchronizing pulse produced at the zero crossing and guided due capacitor rapid discharge to zero The resulting thereby sawtooth Lh is switched to the averaging unit 7, and whose output voltage is amplified by a factor of 2
Durch Vergleich der mittels des Umkehrverstärkers 8 polaritätsmäßig angepaßten Referenzspannung Us mit der Ausgangsspannung LZ7 des Mittelwertbildners 7 in einem Vergleicher 10 ergibt sich die durch den Regler 6 verstärkte Ausgangsspahhung Ui, die — zusätzlich auf den Integratoreingang des Sägezahngenerators 2 geschaltet — dafür sorgt daß der Spitzenwert der Sägezahnspannung i/2 immer den Betrag der Referenzspannung Us annimmt Die Symmetrie der Ausgangsimpulse ist damit lediglich von dei Genauigkeit der Bauelemente (Bewertungswiderstände, Operationsverstärker) abhängig. Die Toleranz des Integrationskondensators des Sägezahngenerators 2 kann jedoch 20—30% betragen und damit aus den gängigen Listen ausgewählt werden.By comparing the polarity-adjusted reference voltage Us by means of the reversing amplifier 8 with the output voltage LZ 7 of the averaging unit 7 in a comparator 10, the output voltage Ui amplified by the controller 6 results, which - additionally connected to the integrator input of the sawtooth generator 2 - ensures that the peak value the sawtooth voltage i / 2 always assumes the magnitude of the reference voltage Us . The symmetry of the output pulses is therefore only dependent on the accuracy of the components (evaluation resistors, operational amplifiers). The tolerance of the integration capacitor of the sawtooth generator 2 can, however, be 20-30% and can thus be selected from the current lists.
Frequenzänderungen, die durch Anschluß an Netze anderer Frequenz als 50 Hz auftreten, werden vom Steuersatz durch Selbstanpassung verarbeitet. Wie der Vergleich zwischen 50 und 60 Hz zeigt, ist der Steuerwinkel λι(6ομ*; bezogen auf die jeweilige Frequenz gleich dem Steuerwinkel Λ350 /fa>Frequency changes that occur due to connection to networks with a frequency other than 50 Hz are recognized by the Tax rate processed by self-adjustment. As the comparison between 50 and 60 Hz shows, the control angle is λι (6ομ *; based on the respective frequency equal to the control angle Λ350 / fa>
Der Frequenzbereich wird durch die Synchronisierimpulsbreite und den Ausgangsspannungshub des Reglers 6 begrenzt Eine Selbstanpassung im Bereich 25 -100 Hz ist jedoch möglich.The frequency range is determined by the synchronization pulse width and the output voltage swing of the controller 6 limited A self-adjustment in the range 25-100 Hz is possible.
F i g. 5 zeigt die erfindungsgemäße Schaltungsanordnung eines 6-pulsigen Steuersatzes, wobei je Netzphase (ein bis drei Strich) jeweils ein Steuersatz aber nur eine gemeinsame Referenzspannungsquelle 5 und ein gemeinsamer Umkehrverstärker 8 vorgesehen sind.F i g. 5 shows the circuit arrangement according to the invention of a 6-pulse control set, with each network phase (one to three lines) one tax rate each but only one common reference voltage source 5 and one common Reversing amplifiers 8 are provided.
